Observations on the Embryonic Development of Freshwater Pulmonate Snail Lymnaea Acuminata (lamarck, 1822) (gastropoda: Mollusca)
Molluscs have played important role in strengthening our knowledge of fundamental processes in developmental biology, with the common pond snail Lymnaea stagnalis contributing greatly to this body of literature for nearly a century (Gatenby, 1919; Sturtevant, 1923; Canton and Sloof, 1977). The morphological, morphometric and behavioral aspects of development of L. stagnalis have been well docum...

متن کاملSynonymy between Lymnaea bogotensis Pilsbry, 1935 and Lymnaea cousini Jousseaume, 1887 (Gastropoda: Lymnaeidae).
The lymneid snail Lymnaea bogotensis Pilsbry 1935 is synonymized with L. cousini Jousseaume 1887, based on morphological comparisons of the reproductive systems. The shell, renal tube, and reproductive system are described and illustrated from specimens collected in the type locality and the municipality of Paipa, Colombia. Bibliographical records reveal L. columella to be the commonest lymneid...
